Restricted content publishing with search engine registry

ABSTRACT

A processor-implemented method is provided. The method may include providing a content registry with at least one application program interface (API) to manage a plurality of entries stored in the content registry. The method may also include providing access to the plurality of entries by a pre-authorized search engine to the content registry in response to a search requested by an authorized requester.

BACKGROUND

The present invention relates generally to the field of computers, and more particularly to search engines.

Search engines (SEs), such as Google (Google® and all Google®-based trademarks and logos are trademarks of Google and/or its affiliates) or Yahoo® (Yahoo® and all Yahoo®-based trademarks and logos are trademarks of Yahoo! Inc. and/or its affiliates) typically use several techniques to crawl or index web pages. Such techniques basically follow links on pages to other pages. Then the pages are sorted by content (and other factors) and this information is indexed. Algorithms and ranking is then used to deliver the best results for search queries. Some SEs such as Google® also enable content owners to use Rich snippets (e.g., microdata, microformats, RDFa, and Data Highlighter) which are the few lines of text that appear under every search result and are designed to give users a sense for what is on the web page and why it's relevant to their query.

DETAILED DESCRIPTION

Detailed embodiments of the claimed structures and methods are disclosed herein; however, it can be understood that the disclosed embodiments are merely illustrative of the claimed structures and methods that may be embodied in various forms. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of this invention to those skilled in the art. In the description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments.

Embodiments of the present invention relate generally to the field of computers, and more particularly to search engines. The following described exemplary embodiments provide a system, method and program product to, among other things, publish restricted content (i.e., a content that requires a pre-authorization to access it) with search engine registry. Therefore, the present embodiment has the capacity to improve the technical field of search engines by discovering weblinks where the source of the links is inaccessible to search engines (SEs). More specifically, the present embodiment may enable the content being searched to be visible to the public domain or at targeted requesters (e.g., users) so the SE is enabled to quickly list these links as part of the search results returned to the requester.

As previously described, Search engines (SEs) typically use several techniques to crawl or index web pages. Such techniques basically follow links on pages to other pages. Then the pages are sorted by content (and other factors) and this information is indexed. Algorithms and ranking is then used to deliver the best results for search queries. Some SEs also enable content owners to use Rich snippets which are the few lines of text that appear under every search result and are designed to give users a sense for what is on the web page and why it's relevant to their query.

Today content owners have to expose all relevant links through their public site in order for it to be discovered and indexed by a SE. However, several use cases exist where content owners may want to expose web links to the public domain or at targeted users as part of the search results when certain queries or tags are used. For example, military operations or strategic research initiatives may want to expose links to documents that can be searched and downloaded by partner organizations but not host the content in the public domain. Additionally, there are commercial examples where premium or paid members would want to search for content specifically targeted at their level of membership without having to login to the site in order to manually locate it. Currently, there are no mechanisms to access or include in search engines any “restricted” (i.e., requiring pre-authorization to access) links. In some scenarios, organization like IEEE, ACM, etc., may create public web pages with just abstracts or short descriptions or articles whereas the full article will be restricted. In these cases, additional web pages need to be maintained for each of the articles in their internal websites or databases which may require more resources and be cumbersome to maintain.

As such, it may be advantageous, among other things to provide restricted content publishing with search engine registry, whereby the restricted content may be restricted or unrestricted and requires pre-authorization for a user to access the content. The present embodiment may provide a way of discovering web links (which can include links to any type of data, restricted content, unrestricted content, content which may reside behind a corporate firewall, content that requires pre-authorization to access, etc.) where the source of the links is completely inaccessible to search engines (SE). The presence of the content (in the form of web links) being searched can be visible to the public domain or at targeted users so the method enables the SE to quickly list these links as part of the search results returned to the user. Benefits of the present embodiment may include the ability to discover these links quickly, avoiding the need to spend a considerable amount of time searching or viewing pages manually. Additionally, content owners may expose links to a SE without having to include it on their public sites. For example, premium or paid members may be able to locate content through a SE without content owners having to provide access or rich snippets to the SE.

According to at least one implementation, the present embodiment may provide a links registry (i.e., a content registry) which is accessible to content owners for contributing links relating to their domain and SEs to consume the information and return such information as part of search queries. Additionally, the content owners may be able to update the registry using an application program interface (API). The registry update may include the links and their relevant metadata using, for example, an XML/JSON post. Then the SEs may subscribe to the links registry to receive new content when it is updated in order for the information to be utilized in the SEs indexing or caching solutions without having to crawl the web pages as a result of the content possibly being restricted and access not existing for the SE. As such, when a search query is executed and relevant information exists in the registry based on tags, keywords, or metadata etc., the SE may return the relevant information as part of the result set allowing for quick discovery of the links.

The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

The following described exemplary embodiments provide a system, method and program product to enable restricted content publishing with search engine registry.

According to at least one implementation, the present embodiment may allow a user to use a search engine, such as Google®, to access restricted information (i.e., restricted or unrestricted information that requires pre-authorization for a user to access it) within a private domain, such as a corporate domain after identifying the user as having appropriate permissions to access the restricted information. For example, an internal corporate article or presentation may be made available in both slide share (i.e., on the public domain) and on a corporate domain, (such as IBM's w3 internal corporate domain). However, the corporate domain version may contain additional restricted information. As such, the present embodiment may allow an authorized user of the restricted information to search for the content using an external search engine, such as Google® and using the links registry or metadata may identify the user searching for the content as an authorized user within the corporate domain and therefore, expose the restricted links within the corporate domain in the search results (possibly in a separate section) for user consumption.

Additionally, a corporation, such as IBM or Apple may share restricted content (behind a firewall) with business partners that have authorized access to the restricted content. For example, Apple may allow the restricted content to be searchable through a public search engine, such as Google®. As such, using the links registry or metadata, Google® may identify the user as an Apple employee searching for the content and as such, expose the restricted content in the search results for consumption by the user authorized user. Furthermore, only the link and associated metadata (may be a short description) are exposed. Therefore, the full content may still have restricted access. As such, by providing the link in the registry, the present embodiment is publishing the presence of a document or page, however, access to it is still restricted. For example, with respect to an Association for Computing Machinery (ACM) journal article, the link to the article may be exposed to conventional search engines, however, the access to article is limited to ACM members or other paid subscribers.

Furthermore, some journal articles, such as the Institute of Electrical and Electronics Engineers (IEEE) or the Association for Computing Machinery (ACM) are available only to their members or paid subscribers. Currently, such journal articles share the title, ISBN #, abstract, etc. in public websites for search engines to discover. However, rather than having to share such information, they may be able to provide “trusted link information” to Google®, for example, without maintaining public abstract pages. Also, based on the same concept, the present embodiment may allow airlines or retailers to provide special offers to exclusive club members, such as Platinum or Gold Club members.

Referring to FIG. 1, an exemplary networked computer environment 100 in accordance with one embodiment is depicted. The networked computer environment 100 may include a computer 102 with a processor 104 and a data storage device 106 that is enabled to run a software program 108 and a Restricted Content Publishing with Search Engine Registry Program 116A. The networked computer environment 100 may also include a server 114 that is enabled to run a Restricted Content Publishing with Search Engine Registry Program 116B that may interact with a database 112 and a communication network 110. The networked computer environment 100 may include a plurality of computer 102 and servers 114, only one of which is shown. The communication network may include various types of communication networks, such as a wide area network (WAN), local area network (LAN), a telecommunication network, a wireless network, a public switched network and/or a satellite network. It should be appreciated that FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements.

The client computer 102 may communicate with the Restricted Content Publishing with Search Engine Registry Program 116B running on server computer 114 via the communications network 110. The communications network 110 may include connections, such as wire, wireless communication links, or fiber optic cables. As will be discussed with reference to FIG. 5, server computer 114 may include internal components 502 a and external components 504 a, respectively, and client computer 102 may include internal components 502 b and external components 504 b, respectively. Client computer 102 may be, for example, a mobile device, a telephone, a personal digital assistant, a netbook, a laptop computer, a tablet computer, a desktop computer, or any type of computing devices capable of running a program, accessing a network, and accessing a database 112. According to various implementations of the present embodiment, the Restricted Content Publishing with Search Engine Registry Program 116A, 116B may interact with a database 112 that may be embedded in various storage devices, such as, but not limited to a mobile device 102, a networked server 114, or a cloud storage service.

As previously described, the client computer 102 may access the Restricted Content Publishing with Search Engine Registry Program 116B, running on server computer 114 via the communications network 110. For example, a user using a client computer 102 and a search engine, such as Google®, may be allowed to access restricted information within a corporate domain after being identified as having appropriate permissions to access the restricted information. For example (as previously described), an internal corporate article presentation may be made available in both slide share (i.e., on the public domain) and on a corporate domain. However, the corporate domain version may contain additional restricted information. As such, the Restricted Content Publishing with Search Engine Registry Program 116A, 116B may allow an authorized user of the restricted information to search for the content using an external search engine, such as Google® and using the links registry or metadata may identify the user searching for the content as an authorized user within the corporate domain and therefore, expose the restricted links within the corporate domain in the search results to the user. According to the present embodiment, only the link and metadata or short description may be exposed through the registry (enough for the SEs to index/tag for searching). The Restricted Content Publishing with Search Engine Registry method is explained in more detail below with respect to FIGS. 2-4.

Referring now to FIG. 2, an exemplary illustration 200 of the components associated with the Restricted Content Publishing with Search Engine Registry Program 116A, 116B in accordance with one embodiment is depicted. The Restricted Content Publishing with Search Engine Registry Program 116A, 116B may include an Agreement 202. The Agreement 202 is established between content providers, such as IBM and search providers, such as Google® or Yahoo® to ensure the content is from a trusted source. As such, the content owners may use an application program interface (API) 204 (i.e., a “plug in” to facilitate integration of new features into existing applications) to post new content in a different format to a Links Registry 206. According to at least one implementation, the Links Registry 206 registry may accept incoming requests, perform relevant validations, spam prevention, etc. and store the content in a database 112 (FIG. 1). The Links Registry 206 can be hosted by the SE or any other 3rd party provider. Additionally, the Links Registry 206 will notify or push new content to subscribing SEs when content has been posted.

Referring now to FIG. 3, an operational flowchart 300 illustrating the steps carried out by a program for restricted content publishing with search engine registry according to at least one embodiment is depicted. As previously described, the present embodiment may allow an authorized user of restricted or unrestricted information to search for the content using an external search engine. Then, using the Links Registry 206 (FIG. 2) or metadata, the Restricted Content Publishing with Search Engine Registry Program 116A, 116B (FIG. 1) may identify the user searching for the content as an authorized user within the corporate domain and therefore, expose the restricted links within the corporate domain in the search results to the user.

Therefore with respect to FIG. 3, at 302 an agreement is established between content providers. For example, an agreement may be established between a content provider, such as IBM and search engines, such as Google® or Yahoo® to ensure the content is from a trusted source. According to at least one implementation, such an agreement may be a monetized service.

Next at 304, content owners will use an API to post a new content format to a registry which includes the links and relevant metadata. As such, content owners may use an API to post the content in a format such as Extensible Markup Language (XML) or JavaScript Object Notation (JSON) format to the Links Registry 206 (FIG. 2). The content format includes the links and relevant metadata associated with the content. XML is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. JSON is an open standard format that uses human-readable text to transmit data objects consisting of attribute—value pairs. It is used primarily to transmit data between a server and web application, as an alternative to XML.

Then at 306, the Links Registry 206 (FIG. 2) will accept incoming requests, perform relevant validations, spam prevention, etc. and store the content in a database 112 (FIG. 1). According to at least one implementation, the Links Registry 206 (FIG. 2) can be hosted by the SE or any other 3rd party provider.

Next at 308, the Links Registry 206 (FIG. 2) will notify or push the new content to subscribing SEs when the content has been posted. Then at 310, the SEs will accept the new incoming changes into their indexing or caching solutions. As such, the SEs will not have to crawl pages since access now exists to the restricted content. Optionally, the contents of the registry may be fully open to the commercial SEs so that they can use this information for their internal indexing. As such, the present embodiment does not have to “push” or receive “notification” by the registry to SEs. The SEs can include the registry as part of their crawl/search/match.

Next at 312, the SEs will return these web links and relevant content provided for search queries to targeted users based on the links' metadata.

An example registry post in XML (JSON or anther format can also be used) may include the following:

1. The domain it should be associated with, when it should be published and if there is an expiration date for the entry.

2. Tags and Description can be used by the SE for index/caching purposes as well as all the other fields.

3. URL is the link needed to be injected into the search results which could be restricted links to content behind a corporate firewall, premium site, etc.

4. Netrange would be the targeted users/domain for which the links would be exposed in search results.

5. Results element can be used to optionally inject any other information with the link into the search results e.g. branding, etc.

An example registry post in XML may be illustrated as follows:

<?xml version=“1.0” encoding=“UTF-8” ?> <register domain=“ www.ibm.com ” publish-on=“2014-05-31” expires-on= “2015-01-31” > <post> <tags>collaboration,blueflex</tags> <url>https://w3.ibm.com/restricted/blueflex/index.html</url> <netrange>192.168.0.0 - 192.168.255.255 </netrange> <results render=“true” > <description>Information relating to the new release of connections code name BlueFlex.</description> <category>Software</category> <author>IBM</author> <feature><![CDATA[<h3>BlueFlex is here!</h3><img src=‘http://www.ibm.com/public/blueflex.jpg’ />]]></feature> </results> </post> </register>

It may be appreciated that FIG. 3 provides only an illustration of one implementation and does not imply any limitations with regard to how different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements. For example, content owners may optionally provide short description, tags or other relevant information to be used in the search and displaying as part of search results.

According to at least one implementation, the present embodiment may provide a way to register restricted content for search engine reporting which includes providing a content registry (i.e., a links registry) with interfaces, such as an application programming interface (API) to create, read, update, delete (i.e., CRUD or change) entries in the content registry whereby the entries include links and metadata for the restricted content. As previously explained, the present embodiment may provide access to the entries by a pre-authorized search engine (SE) to the content registry and may further validate entries input to the registry before storing the entries and return the entries to the pre-authorized search engine based on matching criteria selected from a group consisting of tags, keywords, and metadata.

The method may further include providing an interface for automatic notification of changes to the entries to the pre-authorized search engine to facilitate re-indexing or caching of the entries by the pre-authorized search engine using the latest content from the registry. The entries may be stored in the registry in an interchange format (for example, XML, JSON). The pre-authorized search engine may be determined by an agreement (i.e., contract) between the restricted content providers and the search engine. Furthermore, the agreement may have rules for data exposure based on user criteria. Therefore, the restricted content and web links may be offered as part of the search results only to target search engine users specified by the agreement. As such, the targeted search engine users are identified through mechanisms selected from a group consisting of single sign on tokens (e.g. using openid or SAML), access control tokens (e.g. IEEE authentication token or partner authentication token), OAuth tokens (e.g. Google® OAuth tokens), and source network address (e.g., IBM intranet users may present source IP addresses for known public gateways belonging to IBM labs and specified in the agreement). The authorized user may be identified by the search engine (SE) through the use of a decentralized authentication and authorization protocols between the search engine (SE) and the restricted content provider acting on the links and metadata associated with the restricted content and according to terms and conditions included in the agreement between the restricted content provider and the search engine (SE).

Furthermore, some advantages of the present embodiment may include: restricted links and/or links to content that may exist behind a corporate firewall to be made searchable through a SE allowing for quick discovery; content owners may expose links to a SE without having to include these links on public sites in order for the links to be discovered through existing crawling/indexing algorithms or not having to provide additional public web pages by content owners; optionally, content owners may provide short description, tags or other relevant information to be used in the search and displaying as part of search results; and content owners may make these links visible (through the SE) for targeted users only (e.g., employees or business partners).

The present embodiment is focused on restricted content and allowing pre-authorized public search engines to utilize only the metadata associated with the content which is stored in the registry along with restricted URLs pointing to the actual content. Furthermore, the present embodiment enables the commercial search engines to search and report web pages which may be restricted to a subset of and audience, such as employees of a specific company. As such the existence and source location of the pages and documents may be reported to authorized users of such information, however, the access to the actual pages and documents themselves may not be provided. More specifically, the public search engine may not have access to the whole content but only to metadata associated with the content for indexing and tagging purposes. As such, the actual content may never be tagged or indexed. The public search engine is used to expose only restricted links to the actual content as part of search results. Additionally, the restricted URLs and metadata in the search result are exposed only to targeted users identified and access may be controlled using different mechanisms such as single sign on tokens (e.g., using openedlD or SAML), access control tokens (e.g., IEEE authentication token or partner authentication tokens), OAuth tokens (e.g., Google OAuth tokens), and source network addresses (e.g., IBM Intranet users will present source IP addresses for known public gateways belonging to IBM labs and specified in the agreement). Furthermore, the present embodiment may target the public search engine and notify the pre authorized public search engine when results are changed or contributed to the registry by content owners.

Referring now to FIG. 4, an exemplary illustration 400 of an overview of the method steps described in FIG. 3 according to at least one embodiment is depicted. A user using a client computer 102 and a search engine, such as Google®, may be allowed to access restricted information within a corporate domain after being identified as having appropriate permissions 404 to access the restricted information. As such with respect to FIG. 4, content owners may use an API 204 to post a new content format, such as XML 402 to a registry 206 which includes the links and relevant metadata. As such, content owners may use an API to post the content in a format such as Extensible Markup Language (XML) 402 format to the Links Registry 206. As previously described, the Restricted Content Publishing with Search Engine Registry Program 116A, 116B (FIG. 1) may prevent 406 a user from accessing the restricted content information or allow 404 an authorized user of the restricted information to search for the content using an external search engine, such as Google® and using the links registry 206 and metadata may identify and validate 404 the user searching for the content as an authorized user 404 within the corporate domain and therefore, expose the restricted links within the corporate domain in the search results to the user. As such, the publisher 410 may publish the restricted content with search engine registry in the search results to the authorized user. Therefore, according to the present embodiment, the Restricted Content Publishing with Search Engine Registry Program 116A, 116B (FIG. 1) may register links to websites and as such, allow the contents of restricted information to be searchable and accessible by normal search engines to authorized users.

FIG. 5 is a block diagram 500 of internal and external components of computers depicted in FIG. 1 in accordance with an illustrative embodiment of the present invention. It should be appreciated that FIG. 5 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 6, illustrative cloud computing environment 600 is depicted. As shown, cloud computing environment 600 comprises one or more cloud computing nodes 100 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 600A, desktop computer 600B, laptop computer 600C, and/or automobile computer system 600N may communicate. Nodes 100 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 600 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 600A-N shown in FIG. 6 are intended to be illustrative only and that computing nodes 100 and cloud computing environment 600 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 7, a set of functional abstraction layers 700 provided by cloud computing environment 600 (FIG. 6) is shown.
